Answer:
= 34.5
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given = 121.5, then
a₁ + (69 × 1.5) = 121.5
a₁ + 103.5 = 121.5 ( subtract 103.5 from both sides )
a₁ = 18
Hence
= 18 + (11 × 1.5) = 18 + 16.5 = 34.5

<em>Hello there, and thank you for posting your question here on brainly.
</em>Short answer: x = -5
<em>
</em>Why?
The solution to this has a lot of steps. Subtract two from both sides. (2+7/x=3/5 --> 7/x=-7/5) Multiply both sides by x. (7/x=-7/5 --> 7=-7x/5) Multiply both sides by 5. (7=-7x/5 --> 35=-7x) Divide both sides by -7. (-5=x) x = -5
